ECO KIT SUMMARY:

An ECO kit exists for Reliable Transaction Router V2.2D on OpenVMS 
VAX V6.1 through V7.1.  This kit addresses the following problems:

Problems addressed in the RTRVVME0922D kit:

  o  When the last block of a contiguous set within the
     journal contains a particular pattern, with a valid
     record followed by an invalid one, journal re-reads
     the last record over and over again. This caused ACP
     to loop while trying to read a journal.


Problems addressed in the RTRVVME0822D kit:

  o  14-8-258: An error in RTR V2.2D-ECO7 could cause the RTRACP
     process to intermittently BUGCHECK while it was processing network
     i/o. This has now been corrected.

  o  14-8-263: An error in RTR V2.2D-ECO7 could cause the RTRACP
     process to crash while it was reading the RTR journal file if the
     journal data from a previous run of RTR happened to end in
     a particular location. This could result in an inability to
     restart RTR after a failure, or cause the RTRACP to crash
     when taking over activity on behalf of another cluster node
     which had been stopped. This has now been corrected.



Problems addressed in the RTRVVME0722D kit:

  o  Network problems could lead to nodes becoming and
     remaining semi-connected. This state could lead to
     difficulties establishing quorum, as well as frontend
     to router connectivity problems.

  o  Long facility names (31 characters) could sometimes
     cause the RTRACP process to crash with SS$_BADPARAM.

  o  During periods of network disruption when the DNS was
     not available, some network connections were being
     rejected because the address-to-name translations were
     failing. Code has been added to improve this situation.

  o  Some records in the journal could not be deleted, sometimes 
     leading to transactions being seen when not expected.


Problems addressed in the RTRVVME0622D kit:

  o  During a server failover from main to standby nodes, it was 
     sometimes possible for the standby server to get permanently 
     stuck in a WAIT_JNL state. This was mostly noticed on systems 
     using multiple data partitions and error-prone communication 
     links between the backends and routers.

  o  During server failover to a standby node, some standby servers 
     would get stuck in a STANDBY state permanently. This effect was 
     most pronounced when there was a short network link loss between 
     one of the routers and the standby node immediately after the main 
     node failed.

  o  Several errors during creation of a journal file,  especially when 
     duplicate or spurious journal files existed.

  o  Some crashes caused by RTR's inability to cope with DECdtm recovery.

  o  Transaction hangs caused by network glitches involving shadowed 
     multi-participant transactions.


Problems addressed in the RTRVVME0422D kit:                                   
                                                                              
  o  The Reliable Transaction Router ACP could crash if a set of              
     concurrent servers performed a failover to a standby and the             
     failing node's journal was not accessible.                               
                                                                              
  o  A failover to a standby node that was not in the same cluster            
     could sometimes result in the RTR ACP process looping and                
     application processes hanging.                                           
                                                                              
  o  Monitoring a remote node that had many applications running              
     could result in the error message "too much data" instead of a           
     display.  The amount of data that can be handled by remote               
     monitoring has been increased to avoid this problem.  


Problems addressed in the RTRVVME0322D kit:                                   
                                                                              
  o  In the previous ECO version of RTR V2.2, the ASTPRM parameter was        
     not being returned properly by the event AST.                            
                                                                              
  o  Aborted transactions were causing loss of BYTLM quota when a server      
     was using DDTM.                                                          
                                                                              
  o  Some rare crashes could occur (with LIB$_BADTAGVAL or                    
     LIB$_BADBLOADR) caused by double deallocation of dynamic data            
     structures during some race conditions on network link cleanup.          
                                                                              
  o  DECnet/OSI related crashes could occur due to corrupted data             
     packets (e.g., after node shutdown).                                     
                                                                              
  o  A rare refusal of a node to re-establish a connection (due to a          
     DECnet/OSI problem with corrupted optional data in connect request       
     packets) has been corrected. 

  o  On rare occasions, a DELETE FACILITY or TRIM FACILITY command could      
     hang due to a race condition in the internal lock manager.               
                                                                              
  o  A crash could occur in the Remote Client Handler when TCP/IP             
     Services for OpenVMS (UCX) was improperly started on a node.             
     Now RTR just recognizes the condition and does not use TCP/IP in         
     the Remote Client Handler.  The Remote Client Handler needs to be        
     restarted after the UCX problem is cleared, otherwise remote             
     clients using TCP/IP will fail to connect.                               
                                                                              
  o  The RTR$_ABORT reason status RTR$_REPLYDIFF was not documented.          
                                                                              
     RTR may abort a transaction with this status when there has been a       
     failover from one instance of a server to another (for example, to       
     a shadow server) and the replies from the second server do not           
     exactly match those already received from the first server.  RTR         
     aborts the transaction in case the client application context 
     depended upon a single server instance.  The client application          
     should restart the transaction.                                          
                                                                              
                                                                              
Problems addressed in the RTRVVME02D22 kit:                                   
                                                                              
  o  A rare ACP crash caused by an uninitialized network buffer pointer       
     during a network "glitch" such as a network shutdown on a remote         
     node.                                                                    
                                                                              
  o  More graceful handling of network "glitches" such as corrupted           
     network packets.                                                         
                                                                              
  o  Incorrect setting up of the ASTPRM on event delivery.


Problems addressed in the RTRVVME01D22 kit:                                   
                                                                              
  o  On a primary/standby configuration involving multiple router nodes       
     where the backend and frontends were on different nodes, a network       
     link "glitch" could sometimes cause a problem.  The transactions         
     would be replayed to the standby backend node, and these                 
     transactions would then cause the systems to hang.                       
                                                                              
  o  In a shadow server configuration, if one of the sites became             
     unavailable during certain multiple failure scenarios, or if the         
     surviving site was in the minority, the servers would remain             
     waiting for the other site to come back.                                 
                                                                              
     NOTE:  This occurred because the surviving site should recover the       
            transactions stored in the other node's journal.                  
                                                                              
     This was a problem if the other site was really down, since there        
     was no manual override of this wait.    

     In order to fix this problem, the TRIM FACILITY command has been         
     modified so that if the other site is removed from the surviving         
     site's configuration, then the servers will start processing online      
     transactions.                                                            
                                                                              
     Note that this TRIM FACILITY command should be executed on all the       
     nodes in the surviving site.  Also, a corresponding EXTEND FACILITY      
     should be executed on these nodes immediately prior to bringing the      
     failed site back on line.                                                
                                                                              
NOTE:  Please see the Release Notes supplied with this ECO for more           
       details regarding RTR V2.2D.


INSTALLATION NOTES:

  This ECO kit called RTRVVMECO0922D or RTRAVMECO0922D is a
  replacement for any previously installed RTR kit. Standard VMS
  installation procedures are applicable, as described in the RTR
  installation guide.

  If you are using RTR in a cluster,  you need to execute the
  SYS$STARTUP:RTR$STARTUP.COM procedure on all nodes in the
  cluster, apart from the one where the VMSINSTAL is actually
  performed.

  A system reboot is not necessary.

  Note: The OpenVMS VAX kit for RTR V2.2D ECO09 (and previous
  OpenVMS VAX kits) have 4 savesets, i.e. A, B, C, E. The "D"
  saveset is intentionally missing.
